Reviewing and NACK'ing my own patch, I just noticed that everything apart the
usb-otg-vbus renaming is wrong.

The MT6360 regulator node names should not be capitalized as the bindings are
correct in this regard, and there already is one user (genio-1200-evk) apart
from NIO-12L declaring the wrong ones - so, the driver must be fixed, not the
other way around.

This patch will be cleaned up in v2.

Cheers
